What’s New
Version 1.30.0
The layout on iPad has been improved. There’s a new set of keyboard icons to make advantage of the bigger screen, and the graphing mode will use up less space to allow for more space for your graphs
When designing a custom keyboard layout to suit your needs, you now have the option to add dedicated buttons for constants, equations, and units. This also means if TechniCalc doesn’t have a function built-in that you need, you can add it to your equations list then the keyboard, and it will feel like a built-in function
In addition to the improvements for custom keyboards, a new ‘Woodworking’ keyboard joins the Simplified and Advanced layouts. This is a simplified keyboard with quick access to units commonly used in joinery
Calculations using units are now more accurate. Additionally, when performing calculations on units in the standard editor, better defaults are used when conversions are necessary. For example, multiplying 10 inches by 2 gives 1 foot 8 inches. Of course, if the defaults aren’t what you need, the output can always be customised to your preferences
Currencies can now be favourited in the currency conversion mode
The statistics mode now supports up to eight columns, and a few additional statistics have been added
Along side the four built-in output styles, you can now configure your own style to suit your preferences
Ratings and Reviews
An Excellent Useable Solution for Many
First and foremost, I’d like to thank you for developing the best iOS calculator for scientists and engineers. It is simply a joy to use on the iPad, and the features are invaluable. I’m a professor of Physical Chemistry, and the “constants” feature is a huge time saver. I love that recent constants are shown on top for easier access. Also, having the ability to build equations with fillable numbers makes this a great pedagogical tool and a quick way to solve problems using the same equation. I will be encouraging my students to consider this app seriously, and after my class demo today I’m sure they’ll be impressed. I have two suggestions. Saved equations and other settings (e.g. list of common constants) do not carry over to other iOS devices. This syncing is important especially if you’ve created a large number of equations. Secondly, it would be great if there’s an easy way to solve for parameter in an equation. For example, hc/L = 2E-4, where h = Planck’s constant, c = speed of light. Solving for L (wavelength). This is a simple example and I tried using solver mode but doesn’t work. Problems like this don’t need initial guesses. Maple on a PC and Mac does this flawlessly, but their iOS calculator lacks most of the features in TechniCalc. Again, thank you for providing a real useable solution to many people!

Thanks for the five star review - it really helps out! I’ll look into why the solver doesn’t work for that equation. iCloud storage is a good idea. I’ll see what I can do!
Quality Calculator App
A vast improvement over the baseline apple calculator, especially on iPad. The interface is understandable and pleasant, and I can imput complex multi-operation calculations without worrying if I messed up order of operations, like on the apple standard calc.
My only two complaints are 1) The unit converter is time consuming to change units, especially when it's often the same few conversions. It would be nice to have a 'Favorites' menu to save conversions. 2) It'd be useful to have a widget of the app so I can access it without constantly opening the app.
Regardless of the two things, this is still the best calculator app I have used.

Thanks for the review! It really helps out. For quick access, head on over to settings and enable ‘always available’. Then use ctrl + option + / to open the app. I’ll take a look at speeding unit conversion up. If you have any more ideas, you can always email me through the link in the app!
This app is crazy good
This app has everything I need. Design and dark mode is beautiful, and the amount of effort in this app is visible. It has matrix operations, fractions and equation solver. With unit conversions! I no longer fear the problems in English units! I got here from a random Reddit suggestion and your app is just the thing I needed. How is this not in top charts! Get this app, it’s not even comparable to many I’ve had to browse through today!
PS: There happens to be some inconsistencies in signs when you’re working with decimal numbers. The magnitude is correct but the sign is always positive. If you have a forum for bug reports, I can report this bug there, but a great app nevertheless

Thank you so much for this! It means a lot to hear people enjoy the app 😊
Edit: You can email me at technicalc_support@icloud.com. Examples of stuff that's broken would really help so I can fix them in the next release!
